Active suspension with variable roll rigidity distribution ratio
First Claim
1. An active suspension comprising a plurality of actuators such that a corresponding one of said actuators is provided to each vehicle wheel so as to support a corresponding part of vehicle load according to a target load value determined therefor, a transverse acceleration detection means for detecting transverse acceleration of a vehicle body, a means for dividing said vehicle load to be imposed on each vehicle wheel based upon the transverse acceleration detected by said transverse acceleration detection means through adjustment of said target load values, and a control means for controlling each of said plurality of actuators in accordance with said target load value therefor, wherein said vehicle load dividing means is adapted to provide a greater share of the vehicle load due to the transverse acceleration to be born on a rear vehicle wheel as said target load value on a front vehicle wheel at the outside of the turn increases.

Abstract
In order to improve both the stability of the vehicle during a normal turning such as a lane change and the manoeuvrability of the vehicle during a high transverse acceleration turning, in an active suspension having an actuator adapted to increase or decrease vehicle height at the corresponding portion so that the rolling of the vehicle body is suppressed by a control of the actuator carried out in response to transverse acceleration of the vehicle body, the roll rigidity distribution ratio is shifted toward rear vehicle wheels according to increase of the loads on the vehicle wheels at the outside of the turning.
